To create a beautiful garden with year-round appeal it’s essential to pick the best plants, and few celebrate the seasons more than colourful cornus, the Horticultural Trades Association’s (HTA) Plant of the Moment for November.
Commonly called dogwoods, these reliable and hardy shrubs provide a luscious leafy backdrop to summer flowers. As a final fanfare their foliage is transformed into a rainbow of colours through autumn before fluttering away to reveal brilliant wand-like stems.
This seasonal transformation is just the start of a host of new planting partnerships that can be enjoyed right through until spring. During winter the brightly coloured stems of dogwoods catch sunlight to create dazzling displays. Small gardens might only have space for a single plant, so position it where the low piercing winter sunlight will shine through, catching stems in its spotlight.
Many shrubby dogwoods also carry clusters of tiny flowers through summer. These are usually a creamy-white colour, and these often lead on to form dense heads of white berries in autumn.
Shrubby dogwoods grow well in almost any soil, even moist sites and heavy clay ground. They’ll grow best in a sunny position, but will tolerate some shade. Contrasting colours always work well when developing planting combinations, so consider planting groups of two or more dogwoods together.
Try planting dogwoods in large patio containers to create seasonal displays with a difference, under-planting them with low winter bedding, leafy perennials and small shrubs.
There are dozens of plants to choose from as partners for dogwoods. Some can be planted behind them as a background to enhance the visibility of their stems, while others provide flowering companions through winter. Several low growing plants, like bergenia and heuchera, can be planted around clumps to carpet the ground, or underplant with early flowering bulbs like snowdrops, crocus and narcissus. Choose carefully and your garden displays really will become a celebration of colourful cornus.
POPULAR DOGWOOD VARIETIES FOR THE GARDEN
For summer foliage and winter stems:
Cornus alba varieties – such as ‘Elegantissima’, ‘Aurea’, ‘Spaethii’, and Siberian dogwood ‘Sibirica’
Small trees with attractive flowers and foliage:
Cornus controversa ‘Variegata’ (AGM)
For winter flowers:
Cornus mas – dainty yellow flowers in winter, red fruits in late summer
TOP TIPS FOR PLANNING AND PLANTING
Where dogwoods are specifically being grown for their winter stems they’ll need annual pruning. This is simply done by cutting all stems down to their woody base close to ground level every spring. This encourages new stems to develop during the year, and it’s these you’ll enjoy the following winter.
If you fancy having a go at propagating your own dogwoods then try taking hardwood cuttings. Once leaves have fallen, lengths of stem can be prepared and inserted into slits in the ground filled with gritty sand. Heal in firmly and keep watered if conditions are dry. Cuttings should root over spring/summer and produce well rooted new plants by next autumn. They’re fun to take, so check online for full advice on taking hardwood cuttings.
